EZ-RJ45 CAT6+ STRAIN RELIEFSThese strain reliefs are designed specifically for the EZ-RJ45 Cat6+ connector. The unique design allows the strain relief to be crimped with the connector, making it an integral part of the complete assembly. Once terminated the strain relief will not pull off the connector. Electrical performance of the termination is optimized by maintaining the bend radius of the cable exiting the rear of the connector, per Category 6 requirements. (they look good too!)Note: These strain reliefs only work on the Cat6+ plugs.
